I am finding the same problem when I open your site in mobile view. It even happens when I use [safe-mode](https://meta.discourse.org/t/how-to-use-discourse-safe-mode/53504) to open the site.

The errors I’m seeing in the console are:

```plaintext
GET https://community.bcro.org/categories.json 500
Error while processing route: discovery.categories

```

When I open the site in the desktop view, there are no errors on the categories page.

You can load the mobile view of your site on a desktop by going to `https://community.bcro.org/?mobile_view=1`. If you do this, and open your site’s error log page (Admin / Logs / Error Logs), you should see an error message that will give more details about what is going wrong. To filter the logs, deselect the `Debug`, `Info`, and `Warning` checkboxes from the bottom left of your logs page.

Let us know what you find in the logs.
